On centos with cmake 2.8.12.2:
CMake Error at cmake/AddEventLibrary.cmake:92 (export):
export called with target "event_extra_shared" which requires target
"event_core_shared" that is not in the export list.
If the required target is not easy to reference in this call, consider
using the APPEND option with multiple separate calls.
But on newer cmake I guess everything is ok.
Fixes: 7182c2f561570cd9ceb704623ebe9ae3608c7b43 ("cmake: build SHARED
and STATIC libraries (like autoconf does)")
This patchset fixes win32 builds after some previous patches (referenced
in particular commits), and also removes some quirks for win32.
* win32-fixes:
test: do not return void
log/win32: fix exporting extern variable
log-internal: missing extern "C"
log: remove USE_GLOBAL_FOR_DEBUG_LOGGING
cmake: Export missing symbols for win32
cmake: eliminate EVENT_BUILDING_REGRESS_TEST, since we link with shared libs
test: windows doesn't have WNOWAIT
cmake: clean not used #defines from event-config.h
cmake: add <pthread.h> only for non-win32
This patchset adds next missing things (in compare to autotools):
- pkgconfig
- event_pthreads/event_openssl
- compile shared/static libraries always
And some fixes, because it will not build after fixing other things:
- export missing symbols for cmake (-fvisibility=hidden)
* cmake-missing-bits:
cmake: support visibility for AppleClang too
cmake: fix export absolute path and relative path and cleanup a bit
cmake: generate and install pkgconfig files
cmake: build SHARED and STATIC libraries (like autoconf does)
cmake: add missing event_openssl/event_pthreads libraries
Export symbols for -fvisibility=hidden (under cmake)
Refs: #246
Defaults apple linker behaviour is -two_levelnamespace, and you cannot
use "-undefined suppress" with it, so let's link non event_core with
event_core library to avoid undefined symbols.
Remove next vars, since I don't think that somebody want to change it:
- bin
- lib
- include
And fix exports problem:
CMake Error: INSTALL(EXPORT "LibeventTargets") given absolute DESTINATION "/usr/lib/cmake/libevent" but the export references an installation of target "event_core_static" which has relative DESTINATION "lib".
Since they are useful for debugging, and if autotools build them then
cmamke has to do this too, to make migration more simple.
And now:
- tests: uses shared libraries (since this is upstreams one)
- other binaries: uses static libraries
This removes next private config:
- EVENT__NEED_DLLIMPORT
This will remove openssl requirement if you don't use it (i.e. if you
not link with openssl_pthreads).
Plus it fixes some linking dependencies:
- libm required only for test-ratelim
And fix some coding style alignment issues.

First of all we don't really need two of them, and also with apple-clang
it will fail (because of our checks in cmake), so just exclude it from
the build matrix.
Nowadays mostly all supported OS'es has this wrappers, and some of them (like
SmartOS) has wrappers but doesn't have __NR_epoll* defines for syscall numbers,
so just drop them (instead of adding yet another check int cmake like autotools
has, since this will break building in cross-compile environment).
Also one minor note, configure doesn't added epoll_sub.c either, since it check
epoll_create() in runtime.
And I tested it in SmartOS and it even works (`make verify`).
Fixes: #463
Fixes in cmake, to make it more like configure and support some
cross-compiling.
* cmake-configure-fixes-v2:
cmake: fix extracting of the version from git (check for number of matches)
Detect arch4random_addrandom() existence
Use off_t instead of ev_off_t for sendfile() (fixes android build)
cmake: detect _GNU_SOURCE not by __GNU_LIBRARY__ only (fallback to _GNU_SOURCE)
Check for WNOWAIT in waitpid() in runtime (not in cmake/configure)
cmake: add <pthread.h> into CMAKE_REQUIRED_INCLUDES for sizeof(pthread_t)
cmake: fix values for #cmakedefine
cmake: drop duplicates from event-config template
cmake: add value for the #cmakedefine macros (like autoconf)
cmake: Fix checking of enum values from sysctl.h
Because checking in cmake breaks cross-compiling.

v2: use waitid() with WNOWAIT
v3: use WNOWAIT only if it available in waitpid(), because not all netbsd
supports it
Before this patch for cmake we had:
#define EVENT__HAVE_ACCEPT4
/* #undef EVENT__HAVE_ARC4RANDOM */
While autotools has:
#define EVENT__HAVE_ACCEPT4 1
/* #undef EVENT__HAVE_ARC4RANDOM */
CheckSymbolExists do not do this, so add new CheckConstExists that will
use CheckCSourceCompiles() to check this.
v2: use set() instead of string(APPEND)
* fix-openssl-linking:
sample/https-client: use ERR_remove_*state() when we have them
Do not check for ERR_remove_thread_state() (do not link ssl into every library)
Closes: #476
This reverts commit c4e9d9bd662de7f575f2172c160795d452ebe709
("sample/https-client: check for ERR_remove_thread_state() existence").
Calling AC_SEARCH_LIBS() modifies LIBS - -lcrypto incorrectly
ends up in LIBS, and thus linked to by libevent_core.so.
Checking for ERR_remove_thread_state should no longer be needed
because it was introduced in openssl 1.0.0, and the previous line
0.9.8 had support discontinued at the end of 2015.
Fixes: #473
By setting the CMake minimum version to 3.1 CMake automatically
adds the correct magic to make the library relocatable on
the filesystem (instead of burning the location of the library
at link time into the binary).
ex:
otool -L bin/http-connect
bin/http-connect:
@rpath/libevent_extra.2.2.0.dylib (compatibility version 2.2.0, current version 0.0.0)
/usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.8)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1238.0.0)
Fixes: #468 (cherry-picked)
Currently a static (Debian) certificate path is used by default, which
can be overridden using the -crt parameter. This commit changes the
default behaviour such that the openssl default certificate store is
used, unless overridden by -crt.
